BIRDS OF NORTH DAKOTA 



135 — i20a. Western Mghthawk. Chordeiles yirgiuiauus henryi. 



Intermingling and breeding with virginianus. Dr. Bishop has a series of 

 skins which are redescribed and admitted as Bennett's Nighthawk, and same 

 will be found, I think, to be the predominating nighthawk in this region. 



136 — 423. Chimney Swift. Chaetura pelagiea. 



A rare straggler. Does not occur every year. 



137 — 428. Ruby-throated Hummingbird. Trochilus colubris. 



Not uncommon on prairies. Tolerably common and breeds in Turtle 

 Mountains. 



138 — 444. Kingbird. Tyrannus tyrannus. 



Very common summer resident. When trees or bushes are not at hand, 

 they build their nests on plows, binders, in the tin eave gutters, and I have 

 a record of one nest built on the ground on the bank overhanging a coulee 

 bed. For a long term of years first notes of spring migrants of this species 

 were made on either the 17th or the 19th day of May. 



As We Ranged the Prairies Collecting- in 1S95 



139 — 447. Arkansas Kingbird. Tyrannus rerticalis. 



Common around Devils Lake. Rare at Cando and north up to 1895. (In 

 1910 they equal the Kingbird in numbers around Cando.) Another instance of 

 the changes in the avi fauna as the country settles up. 



140 — 452. Crested Flycatcher. Myiarchus crinitus. 



Rare. Several specimens have been taken in Turtle Mountains. 



141 — 456. Phoebe. Sayornis phoebe. 



Rare. But one specimen for this locality, April, 1895. 



142 — 461. Wood Pewee. Contopus virens. 



Admitted to list, but data on this species very incomplete. 



143 — 463. Yello\v-l)ellied Flycatcher. Enipidonax flaviventris. 



Rare. Breeding in Turtle Mountains.
